Hi
The embedded linux I am working on is Angstrom factory installed on Arm9 kit.

Before working on it, I have to understand Embedded Linux at the deepest level.
I have searched a lot, but there is hardly material available to understand linux from Primary Bootloader to Rootfiles.

Can any one provide me the link for the same??

Try this book by Karim Yaghmour

and try lfs

If you understand how to create a rootfs and manually put a boot loader on a device then you are 50% done.
Next is you have to learn how to cross compile for the target architecture( In your case it is ARM-9 )
then you should try it under a emulator( eg qemu)
Learn how to flash Uboot or any boot loader to your board.
then on boot loader prompt try to load your rootfs through NFS
if it works then put your rootfs on to the medium you planed to boot from.

well this is in a nut shell, but real life situation are always different.

Hope this help.
Ashok.
